Filed Apr. 13, 1961, Ser. No. 102,806 7 Claims. (Cl. 273-1065) Thisinvention relates to an improvement in dual purpose arrow head and dealsparticularly with an arrow which can be used either as a hunting arrowor as a practice arrow.

During recent years the art of hunting game with a bow and arrow hasbecome more and more popular. Certain states have even acted toencourage hunting of this type by providing a lengthened open season forthe hunting of deer and other such game with a bow and arrow. Hunting ofthis type naturally takes considerable skill and practice. Persons whoare adept at hunting in this manner usually spend many hours in practiceshooting to develop the necessary skill and speed.

One of the obstacles which has been encountered lies in the fact thatunder normal circumstances a different type of arrow is used for huntingthan is normally used for practice. Hunting arrows are usually equippedwith pointed blades having diverging sharpened edges so as to penetrateinto the game to the desired extent. However, blades of this type arenot normally used for practice shooting in view of the destruction whichthey cause to targets. If the practice shooting takes place in woodedareas, there is also a considerable danger of injuring the arrowhead ordulling the blades by engagement with trees and underbrush. However, theuse of other arrows as practice arrows sometimes creates difiicultybecause the weights of the arrows may vary, and the flightcharacteristics of the arrow might also vary. Accordingly, it is theobject of the present invention to provide a dual purpose arrow whichmay be used either as a hunting arrow or for practice.

An object of the present invention resides in the provision of anarrowhead including a pair of blades which are pivotally connectedtogether and which are capable of swinging from an extended form inwhich the edges of the blade extend rearwardly and outwardly from thearrow point along diverging lines to a collapsed position in which theblades are substantially completely overlapped, and so that the sharpedges of the blades do not extend beyond the periphery of the arrowhead.When in one position, the arrow may be used for hunting purposes, andwill act similarly to almost any hunting arrow. When in collapsedposition, the blades are virtually confined within the body of thearrowhead, and therefore will not cause damage to targets, and will notbe damaged thereby.

A further feature of the present invention resides in the provision ofan arrowhead which is. diametrically slotted in order to accommodate theblades therebetween. The blades are pivotally connected near theirforward ends to the arrowhead. A sleeve or ferrule is slidably supportedupon the head of the arrow and includes diametricaly extending slotswhich register with the first named slot and through which the bladesmay project. The sleeve also includes a diametrically extending pinwhich extends through a slot in the head end of the arrow at rightangles to the first named slots. This pin extends through cam slots inthe blades. By sliding the sleeve or ferrule in one direction, the pinacts to move the blades into projected position. When the sleeve ismoved in the opposite direction, the blades are pivoted into retractedposition. Means is provided for retaining the sleeve in either extremeposition.

These and other objects and novel features of the present invention willbe more clearly and fully set forth in the following specification andclaims.

In the drawings forming a part of the specification:

FIGURE 1 is a side elevational view of an arrowhead showing the generalarrangement of parts therein.

FIGURE 2 is a plan view of the arrowhead shown in FIGURE 1.

FIGURE 3 is a longitudinal sectional view through the arrowhead, theposition of the section being indicated by the line 33 of FIGURE 2.

FIGURE 4 is a side elevational view of the arrowhead with the blades incollapsed position. 1

FIGURE 5 is a sectional view of the arrowhead in collapsed position, theposition of the section being indicated by the line 5-5 of FIGURE 4.

FIGURE 6 is an elevational view of the two blades removed from theremainder of the arrowhead.

The arrow is indicated in general by the letter A. For the purpose ofillustration, the shaft 10 of the arrow is shown as being a solid rodwhich might be of Wood or other suitable material. However, if the arrowis to be made of metal, such as aluminum, the shaft 10 may be of hollowtubular form. Also in the present illustration,

the arrowhead is shown as including a forward end portion 11 which maybe integral with the main portion of the shaft 10, or which may bedetachably connected thereto.

As indicated in the drawings, the end portion 11 of the arrow A isprovided with a diametrically extending slot '12 which extends into thearrow shaft end 11 from the forward extremity thereof. The forwardextremity 13 of the shaft portion 11 is preferably tapered or beveled asindicated at 13. A pair of blades 14 and 15 are pivotally secured in theslot 12 by a pivot 16. The pivot 16 extends through the forwardextremity 13 of the arrow shaft and through registering apertures 17 and19 near the forward portions of the blades 14 and 15 respectively.

The blades 14 and 15 are generally similar, one blade being reverse ofthe other. The blades may be provided with one fiat side, and the outeredge of the other side of each blade may be marginally sharpened asindicated at 20 and 21 respectively. The forward end of each blade iscut off diagonally as indicated at 22 and 23 respectively and theseedges are marginally sharpened as indicated at 24 and 28 respectively.The blades are elongated and the sharpened edges may curve slightly butin general the blades are no wider than the portion of the arrowhead inwhich they are supported, as will be later described.

The blades 14 and 15 are provided with cam slots 25 and 26 which areangularly related relative to the longitudinal axis of the blades. Thesecam slots 25 and 26 provide a means of pivoting the blades in unison, aswill be later described.

A sleeve 27 which is preferably provided with tapered ends 29 and 30 isslidably supported upon the end 11 with a slot 31 which intersects thepreviously described slot 12 at right angles. A pin 32 extendsdiametrically through the sleeve 27 and extends through the slots 31.

As is indicated in FIGURE '3 of the drawings, the pin 32 also extendsthrough the cam slots 25 and 26 of the blades 14 and 15. When the sleeve27 is moved forwardly toward the forward end 13 of the arrowhead, thepin 32 extends through the forward ends of the slots 25 and 26 and theblades 14 and 15 are swung outwardly so that the sharpened cutting edgesthereon are in outwardly and rearwardly diverging relation. In thisposition, the pointed ends of the two blades are in contiguous relationas may also be seen in FIGURES 1 and 3 of the drawings. By sliding thesleeve 27 rearwardly away from the forward end of the arrow, into theposition shown in amazes FIGURE 4 of the drawings, the pin 32 movesrearwardly in the slots 25 and 26, and pivots the two blades 14 and 15in unison until they are retracted into the slot 12 and the registeringslots 33 and 34 in the sleeve 27. When in the position shown in FIGURE4, the cutting edges of the blades are substantially retracted withinthe confines of the sleeve 27 so that the blades are ineffective. Whenin this position, the arrow may be used as a practice arrow and thelikelihood of injuring the blade is greatly reduced. At the same time,the weight of the arrowhead remains unchanged and the flightcharacteristics of the arrow remain substantially unchanged. As aresult, the same arrow may be used either for practice or as a huntingarrow, and there is no danger of shooting errors due to the fact thatpractice arrows are of one weight and the actual hunting arrows are ofanother. When the blades are in the concealed position illustrated inFIGURE 4 of the drawings, the pointed ends of the two blades which areindicated in FIGURE 4 swing slightly out of registry due to the factthat the pivot cannot well be at the extreme forward end of the blades.However, these pointed ends project but slightly beyond the forwardextremity 13 of the arrowhead body and are protected thereby.

In the preferred form of construction, the arrowhead body 11 is providedwith a pair of parallel apertures 39 and 40 extending therethrough. Theaperture 39 is exposed as the sleeve 21 is moved into its forwardposition illustrated in FIGURE 3 of the drawings, and a small lockingpin 41 may be inserted through the aperture 39 to hold the sleeve 27 inits adjusted position.

When the sleeve is moved rearwardly to the position shown in FIGURES 4and 5 of the drawings, the forward aperture 40 is exposed through therear ends of the slots 33 and 34, and the locking pin 41 may be engagedin the aperture 40 to hold the sleeve in its rearward position. The pin41 may frictionally engage in place, or may be held in place by anysuitable means, and projects from the arrowhead body to the extentnecessary to lie in the path of movement of the sleeve. The blades areof sufficient thickness and strength to withstand the strain to whichthey are subjected.
